ANTENNA.

Application filed July 9,

body and transmitted to a radio receiving setp Another object of theinvention is the provision of an antenna of this character, wherein thebody of the same is of novel form and construction, as it is in the formof an inverted saucer with a companion non-inverted lower portion made apart thereof, which together with the body serves to enclose a series ofsuperposed disks of metal or other conducting material, these beinginsulated from each other and act as condensers for the high frequencyelectric currents picked up by the body, the entire assemblage beingsupported by a standard or post, which has means for attachment theretoof a lead-in wire to a radio receiving set for transmitting the etherwaves thereto.

A further object of the inventionis the provision of an antenna of thischaracter, where- 30 in the construction thereof renders itnondirectional and when in use with a radio set of the receiving typeenables the latter to be more selective and operate with greatereffic-iency than would be obtained if the present known or used types ofnon-directional antennae were employed.

A still further object of the invention is the provision of an antennaof this character, which is extremely simple in construction, strong,durable, thoroughly reliable and eiiicient in its purpose, readily andeasily mounted for use with dispatch, and inexpensive to manufacture andinstall.

Other objects will be in part obvious and in part hereinafter pointedout.

The improvements in the details and arrangement of parts will beapparent from an inspection of the accompanying drawing, in connectionwith the specific description hereinafter contained, and wherein thepreferred embodiment of the invention is disclosed for the purpose ofimparting a full understanding of the same.

In the accompanying drawing Figure 1, is a top plan view of the antennaconstructed in accordance with the invention.

1925. Serial No. 42,398. I

Flgure 2, is a sectional view taken on the.

line 22 of Figure 1, looking in the direction of the arrows.

F1gur e 3, 1s a fragmentary enlarged sed tional view taken approximatelyon the line 22, look ng in the direction of the arrows 3-3, of Figure 1.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, the

antenna A, as a unit comprises an umbrella shaped or inverted saucerlike top section 5,

of conducting material, preferably copper. although it may be made fromany other suitable material forrollecting high fre-" quency electriccurrents, the diameter of said section being of the required dimensionsas the occasion may demand. while within the convexed hollow 6, of thistop section 5, is centrally located a smaller non-inverted saucer shapedbottom section 7, which is likewise made from conducting material forelectric currents, and the edge of this bottom section abuts and issoldered or otherwise secured to the inner surface of the top section 5,to form a unitary structure. A

These top and bottom sections 5, and 7, united as before named forms achamber 9. therebetween, andv passed upwardly through the bottom section7, ccntrallv thereof is a hollow or tubular post 10. the upper end beingsoldered or otherwise secured centrally to the top section 5. while thelower portion of this post extends the desired'distahce beneath thebottom section 7, the latter being also soldered or otherwise fastenedto said post.

The lower end of the post 10. is suitably fitted in an insulator 11,preferably of mica. although it may be of othernon-conductine, material.It is to be understood that this insulator 11, is fastened to anysuitable support (not shown) upon a foundation or other part where itmay be required to erect the antenna for use with a radio set of thereceive ype.

Carried by the post below the bottom section 7, is a binding device 15for the lead in wire of the radio set and in this manner the antenna ishooked up, therewith.

Arranged within the chamber 9. formed by the top and bottom sections 5,and 7, are a series of disks 12, made from metal, and these disks arespaced apart by the inter-post tioning of sheets of insulation 18,therebetween. The disks are fitted tight about the post 10, and certainof the outer disks 12, are of less diameter than the intermediate disks,so that the group will conform to the interior shape of the chamber 9,by reason of the curved surfaces of the top and bottom sections 5, and7, of the antenna.

The top and bottom sections 5, and 7 are formed or have struck therefromannular reinforcing ribs 14, to give strength. to the an.- tenna andtorender the sections rigid.

The disks 12, in their arrangement serve to efliciently collect theether waves and send the same down through the post 10, to betransmitted through the lead-in wire to the radio receiving set.

What is claimed is:

1. An antenna of the character described, comprising a body forming a.chamber, a. post extending centrally into said chamber and fastened tosaid body, and a series of metal plates within'the chamber, andinsulations disposed between said plates, said plates snugly embracingthe post.

2. An antenna of the character described, comprising a body forming achamber, and

chamber and fastened to the top, and a series of plates withinthechamber and snugly em- I bracing said post, said plates beingarranged in spaced relation to each other.

3. An antenna of the character described, comprising an inverted saucershaped top section made from material conducting to high frequencyelectric current, a non-inverted saucer shaped bottom section made fromconducting material and of less diameter than the top section, arrangedwithin the latter and made fast thereto centrally of the same, a postextending centrally through the bottom section and having its upper endfast to the top section, av series of metal disks between the top andbottom sections, spaced from each other and snugly embracing the post,an insulator mounting the lower end of the post, and a binding device onthe post above the insulator for attaching a lead-in wire thereto.

In testimony whereof he afl'ixes his signature.

WILLIAM HENRY HAWORTH.
